DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-mounted work table having a work table mounted on a ladder. The work is mounted on a wall and the work is carried on the work table.

[0002]

2. Description of the Related Art Conventionally, when working in a high place such as an upper part of a wall, it is often the case that a worker goes up a ladder and works on a work table attached to the ladder. As a work table used when working on such a work table, a work table detachably attached to a ladder is known as described in Japanese Utility Model Laid-Open No. 55-9386.

[0003] Referring to FIG. 3, this work table is provided with a scaffold plate 101, a locking piece 102 provided to protrude in front of the scaffold plate 101, and a protruding portion provided below the scaffold plate. The support arm 103 and the support arm 10
3 is provided with a locking piece 104 provided at the lower end. In this worktable, a locking piece 102 provided to protrude forward is hung on a ladder step 105 having an appropriate height, and a locking piece 104 provided at the lower end of the support arm 103 is pulled from the ladder step 105 by the support arm 103. The ladder is mounted on the ladder step 106 one step below, and works on the scaffold plate 101.

[0004]

However, this worktable is difficult to use. That is, when the worker climbs up to the ladder with this work table and arrives below the ladder step 105 having a height suitable for work, the worker projects the ladder step 105 forward of the ladder mounting work table. The engaging piece 102 provided on the lower end of the support arm 103 is hung on the ladder step 106 one step below. Then, since the scaffold plate 101 is attached so as to cover the worker's head, the worker needs to climb over the scaffold plate 101 in order to work on the scaffold plate 101. However, it is difficult to get over the scaffold plate 101 because the scaffold plate 101 protrudes forward from the ladder step. In particular, if the scaffold is wide and protrudes backwards, it will not be possible to cross this scaffold.

[0005] In order to avoid having to climb over the scaffold board 101, the worker climbs up to a ladder step that is one step higher than the ladder step 105 suitable for work, and attempts to attach a ladder mounting work table to the ladder step 105. Then, the waist is bent while being placed on the ladder step, which is one step higher, and the locking piece 10 is attached to the lower ladder step 105.
However, this mounting work is extremely dangerous, and the ladder stairs 1 below the ladder stairs 105 are required.
06, the locking piece 10 provided at the lower end of the support arm 103
There is the problem that multiplying by 4 is even more dangerous and difficult. In the above description, the state when the work table is attached has been described. However, a similar problem occurs when the work table is removed. Therefore, an object of the present invention is to provide a wall-mounted workbench that easily climbs on a workbench attached to a ladder.

[0006]

According to the first aspect of the present invention ,
A workbench Toka Ranaru wall-mounted work bench and wall-mounted ladder,

[0010]

The operation of the wall-mounted workbench according to the first aspect of the present invention will be described together with the method of use. First, lean the wall ladder against the wall
Then, put your foot on the ladder step and climb to above the work table. At this time, the worktable is rotatably mounted by extending the side edges of the worktable to the left and right supports, so that when ascending, the worktable is rotated upward and stored between the supports. Then, the work table can be easily lifted without obstruction.

One end of a string is attached to the work table at a position away from a rotatable side edge of the work table, and the other end of the string is connected to the work table by the rotation shaft.
It can be fixed at a position above the depth length.
Therefore , the string-shaped body can be pulled upward before the wall-hung work table is hung on the wall, and the work table can be placed between the left and right columns.

Thereafter, the string-like body fixed upward is removed. Then, the string-like body that has been pulled at a position away from the rotatably mounted side edge of the work table is loosened, and the work table rotates downward around the side edge. This rotating operation can be performed more quickly if the worker kicks down using his feet. When the worktable is rotated to a substantially horizontal direction, the cord is again fixed above the worktable. Work on this leveled workbench. Also, in claim 2
In the invention, it is assumed that the worktable has been rotated downward from above.
Can, stopper par lateral struts can be fixed in a substantially horizontal position

Since the work table 2 is located between the left and right columns 11, 11, it does not hinder the climbing of the ladder step 12. When reaching the upper part of the worktable 2, the string-shaped body 4 tied upward and fixed is removed.
Then, the worktable 2 rotates around the side edge 21 to a substantially horizontal state. This rotating operation can be performed more quickly if the worker kicks down using his feet.

When the work table 2 is rotated to a substantially horizontal position,
The lower side 25 is locked by the stopper 6 and does not rotate any more, and the work table 2 is held substantially horizontally. next,
As shown in FIG. 1, the string-like body 4 is pulled upward and tied to the upper end 15 and fixed.
From above to work table 2. In this case, the worktable 2 is provided with a double rotation prevention mechanism so that the worktable 2 does not rotate downward by being hooked on the stopper 6 and does not rotate downward by being pulled by the string-shaped body 4. The user can work on the work table 2 with ease.
If the stopper 6 does not rotate down reliably, there is no need to pull the string-like body 4 and fix it upward.

When the operation is completed, the user can descend in the reverse order. That is, moving from the worktable 2 to the ladder step 12,
Remove the knot of the string-like body 4 fixed upward, pull it upward, and place the worktable 2 between the left and right columns 11, 11,
After the string-like body 4 is tied up and fixed, the ladder step 12 is lowered. After descending, the workbench A may be moved to another place.
